Octave uses whatever double precision floating point format your

system uses. These days, for most every system on which Octave runs,

that means it uses the IEEE 64-bit floating point format.

If you're interested in more details about the characteristics of the

floating point arithmetic on your system, I'd recommend running the

paranoia program, available from
